ANALISIS PENERAPAN METODE NIOSH DAN QUALITY FUNCTION DEPLOYMENT TERHADAP RISIKO MUSKULOSKELETAL DI UNIT LIQUID PT. XYZ
Get PDFTujuan dari penelitian ini adalah untuk menganalisis penerapan metode NIOSH Lifting Equation dan Quality Function Deployment (QFD) untuk menilai dan mengurangi risiko gangguan muskuloskeletal (MSDs) di unit Liquid PT. XYZ. Risiko MSD sering muncul dari aktivitas kerja yang melibatkan pengangkatan beban berat secara manual secara berulang, sehingga menimbulkan ancaman serius bagi kesehatan karyawan dan produktivitas perusahaan. Metode NIOSH digunakan untuk menghitung Lifting Index (LI) sebagai indikator risiko ergonomi, sedangkan QFD digunakan untuk menerjemahkan kebutuhan karyawan menjadi langkah-langkah perbaikan rekayasa. Hasil penelitian menunjukkan bahwa aktivitas pengangkatan melebihi ambang batas keselamatan (LI > 1), sehingga berpotensi menimbulkan risiko MSD. QFD mengidentifikasi prioritas perbaikan, termasuk perancangan alat bantu pengangkatan yang ergonomis, perbaikan desain stasiun kerja, dan pelatihan teknik pengangkatan yang aman. Pendekatan terpadu ini bertujuan untuk mengurangi risiko MSD sekaligus meningkatkan produktivitas tempat kerja.

Pengaruh Media Video Animasi terhadap Kemampuan Mengenal Huruf Vokal pada Siswa Disabilitas Intelektual Ringan Kelas IV
Get PDFThis study aims to determine the effect of animated video media on the ability to recognize vowels (a, i, u, e, o) in fourth-grade students with mild intellectual disabilities at Jember State Special Needs School. The research method employed is Single Subject Research (SSR) with an A-B design, consisting of two phases: the baseline phase (A), comprising five sessions, and the intervention phase (B), comprising eight sessions. The results of the analysis in the conditions show that the baseline phase has a percentage score of 35%–50% with a mean level of 42% and a stability range of ±3.7. The data within the stability range is only 1 out of 5 sessions, or 20%, so the data in the baseline phase is declared unstable. In the intervention phase, the percentage score increased from 45% to 85%, with a mean level of 68.7% and a stability range of ±6.3. The data in the stability range is only 2 out of 8 sessions, or 25%, so the intervention phase is also declared unstable. Although both phases exhibited unstable conditions based on the criteria (<80%), there was a significant increase in ability levels from Phase A to Phase B, from a high score of 50% to 85%, as well as a positive level change of +20. No overlap in data (0%) was found, which strengthens the intervention\u27s influence on changing the target behavior. In conclusion, animated video media has been shown to have a positive effect on improving vowel recognition skills in students with mild intellectual disabilities. This study recommends the use of visual-interactive media such as animated videos in special education learning at special needs schools (SLB).

Analisis Berpikir Kritis Siswa SMP dalam Memecahkan Masalah Numerasi Ditinjau dari Persepsi Diri terhadap Kompetensi Matematika
Get PDFThis study aims to analyze students\u27 critical thinking skills in the context of numeracy in terms of their self-perception of mathematical competence. A qualitative approach was used with a case study design, involving four eighth-grade students at a junior high school in Bondowoso who were selected based on the categories of positive, negative, declining, and improving self-perception. The research instruments consisted of a self-perception questionnaire and numeracy questions analyzed using six indicators of critical thinking, namely interpretation, analysis, inference, evaluation, explanation, and self-regulation. Data were obtained through test results and interview transcripts. The results showed that students with positive and increasing self-perceptions were able to meet all six critical thinking indicators, while students with negative self-perceptions met two critical thinking indicators and students with declining self-perceptions met four critical thinking indicators. These findings indicate that positive self-perception tends to contribute to better critical thinking skills, but it was found that students with initially positive self-perception did not necessarily have high critical thinking skills. Thus, the dynamics of self-perception are an important factor that needs to be considered in the development of numeracy-based mathematics learning.
